Final answer:
The incidence of infection is 3-10 times greater for preterm babies compared to other types of babies.
Step-by-step explanation:
The incidence of infection is 3-10 times greater for c) Preterm babies compared to other types of babies such as full-term, post-term, and low birth weight babies. This is because preterm babies are born before full term, which means they have spent less time growing in the uterus and have a higher risk of infection due to their underdeveloped immune system.
